VEGA is the UK Roadmap for the survey decade. Uk astronomy has agreed a clear picture of how the next decade in optical-infrared astrophysics will develop: exploit the existing 8-m telescopes, and survey oarameter soace to feed the VLT, Gemini and ALMA. The surveys are ambitious: one major new mission will see first light each two years over the decade. All will probe at least one new domain of parameter space. Time-domain, multi-wavelength, spectral and kinematic phase space will be explored, each with massive datasets of of rapidly increasing complexity. The scientific goals are ambitious and broad. These missions summarised in the figure below, are WASP, VISTA, Eddington and GAIA. The institutions delivering these missions together form the VEGA partnership. The VEGA partnership represents the highest pririty survey missions in the PPARC scientific strategy. The VEGA missions do not happen without infrastructure. The huge and complex data sets they will deliver motivate (in large part) development of the Virtual Observatory capability and are feasible only because of that capability. AstroGrid provides the VO foundation on which these missions are built. The missions deliver massive and complex raw data sets. AstroGrid delivers infrastructure potential, and the capability for scientists to access fully processed and qualified data. VEGA is the link; the data processing and qualification capabilities which convert raw data into potential science. VEGA is the programme which underpins the PPARC science programme, exploiting and developing the AstroGrid investment. The VEGA missions are not independent. The four missions form a sequence of increasing challenge, with each mission requiring the knowledge and expertise developed by its predecessors for its own success. It is an essential requirement that the four major missions develop as an organic whole, so that knowledge, experience and functionality develops cumulatively. The VEGA programme is to ensure that the mission dependencies are identified and converted from limitations into efficiency savings, as valuable synergies enhancing performance and a set of interfaces strengthening the value of the infrastructure investment in the Virtual Observatory. VEGA is the national overview, providing the big picture, ensuring that developments are consistent ith longer term science strategy and ensuring that investment delivers value. VEGA does not start in isolation: The VISTA mission in particular has major contractual obligations. Thus, we do not envisage a single UK surveys programme. VEGA will develop over time, as the UK programme develops, ensuring that knowledge builds on knowledge, ensuring maximum value for investment and ensuring where beneficial a multi- mission (re-) use of resources and capabilities. VEGA will not add extra management to extant projects. VEGA will provide the critical mass which allows economy of scale. This proposal will create a VO enabled processing system and mission specific, VO enabled, science archives for high priority missions. VEGA will build an integrated UK e-centre of excellence in the VO ready processing of mission data,providing crucial scientific data content to the UK astronomical community through the AstroGrid infrastructure. In particular, VEGA will deliver; The VISTA Data Flow System. The Eddington Data Flow System. The GAIA data flow system. A fully integrated e-centre of excellence in VO processing.
